3 = Pulse signal
a = Trigger signal during double pulse generation is without effect
Δt = Trigger delay between the trigger and the sync signal start; see data sheet
delay = "Double Pulse Delay = 200 ns"; the first pulse starts without a delay
PW = "Double Pulse Width = 100 ns"
"Ext Gated"
Generates the signal triggered by an external gate signal.
Example: Generation of single pulse signal ("Pulse Mode = Sin-
gle") using "Trigger Mode = Ext Gated"
1 = External trigger signal input with "Trigger Input Polarity = Normal" (the positive
slope is active)
2 = Sync signal
3 = Pulse signal
Δt = Trigger delay between the trigger and the sync signal start; see data sheet
delay = "Pulse Delay = 100 ns"
PW = "Pulse Width = 100 ns"
period = "Pulse Period = 300 ns" (time between the pulse start of two consecutive pul-
ses)
a = Gate active duration (pulses are generated during the gate active part)
Remote command:
[:SOURce<hw>]:PULM:TRIGger:MODE on page 583
Pulse Period
Sets the repetition rate of the generated pulse signal.
Remote command:
[:SOURce<hw>]:PULM:PERiod on page 583
Pulse Width
Sets the pulse duration of the generated pulse signal.
Note: The pulse width must be at least 20 ns less than the set pulse period.
Remote command:
[:SOURce<hw>]:PULM:WIDTh on page 584
